Systems, methods and devices for building envelope system

ABSTRACT

A building envelope system includes several elements that aid in reducing heat transfer. Panels combining insulation and radiant barrier materials, a weather-resistant textile (e.g., canvas) cover, tube insulation, a vestibule and strip curtains can all contribute to reducing heat transfer and, correspondingly, reducing energy requirements for heating and/or cooling. The panel can include a tongue and groove or similar (e.g., dovetail) coupling allowing two panels to mate. The panel can include a top insulation layer, top air gap layer(s), radiant barrier layer(s), bottom air gap layer(s), phase change insulation layer(s) and a bottom insulation layer. By including an air gap on both sides of the radiant barrier, the radiant barrier is effective at reducing heat transfer in and out of the shelter.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

A detailed description of systems and methods consistent with embodiments of the present disclosure is provided below. While several embodiments are described, it should be understood that the disclosure is not limited to any one embodiment, but instead encompasses numerous alternatives, modifications, and equivalents. In addition, while numerous specific details are set forth in the following description in order to provide a thorough understanding of the embodiments disclosed herein, some embodiments can be practiced without some or all of these details. Moreover, for the purpose of clarity, certain technical material that is known in the related art has not been described in detail in order to avoid unnecessarily obscuring the disclosure.

It can be difficult to install building envelope technologies on structures inherently designed with limited interior space. Insulation and radiant barrier materials are designed with the implicit assumption that they are being put into a permanent structure and that it does not matter how much space they take up. However, a temporary building, such as a construction trailer or an ISO shelter (a military portable building), does not fit those assumptions. In addition, some homes and offices that are being developed are based on structures made from used shipping containers.

Temporary buildings can have strict limitations on their exterior dimensions. These shelters are often shipped over the road and have to fit within standard lanes. In other embodiments, the shelters are the same size as, or packed into, shipping containers for ocean shipment. Thus, there is a limit on their exterior dimension which inherently limits their interior space to start with. In some solutions, the insulation, rather than the inside space, is compromised. For instance, if six inches of insulation were put on each of the wall and ceilings inside a military ISO shelter, a sixth of the interior space would be lost. Currently, a military ISO shelter has an insulation value of about R4.

In some situations, temporary buildings do not have access to conventional electric infrastructure, but instead use standalone generators, usually based on liquid fuels like diesel or gasoline. In order to use a fueled generator, fuel is shipped in. These small generators operate at about 35-40% fuel efficiency, relative to the 50-55% efficiency of utility-scale generators. In addition, shipping fuel in very small batches to remote locations can cost a substantial amount of money. In some stationary and secure, but remote, locations such as rural Alaska, delivered fuel may cost $6-12 a gallon. Military shipment of fuel into areas where combat operations are ongoing has been estimated to be as high as $400-1,000 a gallon. It is therefore desirable to reduce the fuel required to provide power to the temporary buildings frequently used in remote locations. Reducing the amount of energy used to change the temperature inside the buildings can be significantly helpful with regard to reducing fuel consumption, as maintaining a comfortable interior temperature can be the largest single use of energy, sometimes accounting for 50-70% of the energy used in these buildings.

A mechanism through which people can get the benefit of building envelope technologies is achieved by assembling a building envelope structure outside a temporary building. This outside structure allows for improving the insulation (R) value and also provides a mechanism to provide the benefit from other building envelope heat management technologies that do not have an insulation R value per se, such as radiant barrier. The building envelope panels are lightweight and can be assembled and disassembled and reused several times. The panels act as a building envelope, by providing one or more building envelope systems in a single form that can be used without affecting interior space constraints. In the embodiment described, a panel is constructed of foam insulation, enclosed air pockets, and a radiant barrier, as illustrated in FIG. 2. The insulation provides resistance to thermal conduction and convection. The still air also acts as an insulator and provides resistance to thermal conduction with limited convection. The radiant barrier (e.g., aluminum foil, aluminized Mylar, etc.) works to slow heat transfer by preventing or reducing heat transfer through radiation. The materials in the panels thus work together to prevent or reduce three types of heat transfer: conduction, convection, and radiation.

The portable externally assembled building envelope panels incorporate insulation and radiant barrier to prevent or reduce heat transfer in both directions. In some embodiments, the mounting of the radiant barrier allows for at least three quarters of an inch of airspace on each side, allowing the barrier to work in the same manner in both directions. Where a radiant barrier is mounted directly on one of the pieces of insulation with an air gap only on one side, the barrier blocks or reduces heat transfer in one direction, but it will not block heat transfer in both directions. To block or reduce heat transfer in both directions, airspace or something similar (e.g., vacuum, aerogel) is needed on both sides. A panel with airspace or something similar on both sides can thus block or reduce heat transfer in both directions, allowing the radiant barrier foil to be effective in both winter and summer.

By being able to assemble the building envelope outside the shelter, using panels, the building envelope can be extended to the ground. In some embodiments, these temporary buildings are mounted on railroad ties above ground. A placement crew will position railroad ties, or something similar, and put the temporary building on top of the ties as a foundation. However, this placement allows air to blow underneath the floor. Wind can remove heat that has been conducted to the bottom of the building in winter or provide a continuous supply of new heat to a floor during summer. In some embodiments, the building envelope system can be placed around a building, without attaching it to the building.

In some embodiments, a compressible insulating material, such as an insulating fiberglass, is formed into tubes or placed into plastic tubes. The tubes are placed and/or compressed underneath the building so as to block or reduce the airflow. The panels can be built so as to reach to the ground, further restricting air flow and providing additional insulation around the tubes. The tubes allow a dead air space to be created under the building to prevent or reduce air flow underneath the temporary building. Having the dead air space underneath the temporary building adds some insulation value, as opposed to having a live air space underneath the temporary building from which air movement can remove or add heat through the floor.

In one embodiment, heat transfer is slowed by providing insulation directly by the presence of the foam insulation material, and additionally by the mounting of a radiant barrier inside the foam insulation with air on both sides of the radiant barrier inside the foam insulation, and further by using additional compressible insulation and/or the ability of the panels themselves to cover the air gap between the building and ground and thus to prevent or reduce air from flowing freely underneath the building.

Weather resistance can be achieved by covering the building envelope assembly with a canvas or other weather-resistant tarpaulin that is fitted to a size of the assembled building envelope. The tarpaulin prevents or reduces the foam insulation from being exposed directly to the atmosphere. By using the foam insulation in addition to putting such a cover over it, the building envelope system has been able to survive hostile weather conditions, such as high winds, snow, sleet and rain.

Additional building envelope subsystems can reduce further heat transfer. For example, a strip curtain inside the door and/or a portable vestibule can be used to reduce heat loss through mass transfer (i.e., these systems will prevent or reduce conditioned air from leaving the temporary building and being replaced with unconditioned air from the local environment). In an embodiment, the portable vestibule can be an aluminum frame around the door of the temporary building with a textile over the frame. A vestibule allows enough time for an inside door to close before a person gets to the outside door of the vestibule or allows enough time for an outside door of the vestibule to close before the person gets to the inside door of the temporary building. Either a vestibule or a curtain immediately inside the door allows for the trapping of the conditioned air inside the temporary building as much as possible. However, to the extent that the conditioned air is lost, if a vestibule is present, the air is lost to the weatherized enclosure rather than just directly to the atmosphere. If wind is blowing towards the door, use of a second door slows down the heat loss due to trapping the conditioned air in the vestibule instead of allowing the conditioned air to be swept away by the wind. In some embodiments, the vestibule covering itself can be insulated to have a radiant barrier inside.

Such techniques aid in reducing loss of conditioned air caused by opening or closing the door to the temporary building. In some embodiments, the temporary building is small (e.g., military ISO shelters and shipping container-based buildings are often as small as 8′×8′×20′, and office trailers are commonly about 8′×8′×40′). The door is large relative to the size of the structure and the air contained within. When the door is opened, the conditioned air (e.g., cold air or hot air, depending on season) escapes out the door. The heater or cooling unit is then tasked to make up for the air that was lost. These techniques allow a slowing of the air loss by having a strip curtain and/or vestibule that reduces the amount of heat or cold waft that occurs.

By using the panel technology, heat transfer from the building to the exterior environment, and heat transfer from the exterior environment to the building can be reduced. For example, a bare ISO shelter in the field by itself, without a building envelope system, would have its top metal surface exposed to the sun. Absorption of solar radiation is going to cause the temperature of that metal surface to go up well above the ambient air temperature. On a 90° F. day, the top surface of a bare shelter might be 110° F. or 120° F. The air conditioner inside the shelter is thus working against a temperature of 120° F. By putting the panels up outside the structure, a situation is created in which the effect of the absorption of heat on the top surface of the building during the summer is minimized. Instead of the highest temperature in direct sunlight occurring on the top surface of the building, it now occurs at the top of the insulation. The high temperature at the surface is now a lower temperature than it would otherwise have been, because the insulation product does not heat up as readily as the metal roof. Furthermore, this lower high temperature, at the top of the building envelope, now encounters thermal resistance that slows the transfer of that heat to the interior of the building. The air conditioner will work against a lower temperature and will not have to run as long.

A canvas covering can be placed around the insulation system, which does not transfer heat as easily as the metal surface of a bare shelter. In addition, to the extent there is radiant heat transfer, total heat transfer is reduced by the radiant barrier inside. For example, with the building envelope panels, the top surface is now canvas and will not absorb heat as readily. To an extent that it does absorb heat, the heat will be transferred to the shelter interior through the multiple layers of thermal barriers that resist the heat transfer. The air conditioner will work against a lower temperature and will not have to run as long.

In some embodiments, panels can be constructed with one, two, three or four inches (or other amounts) worth of foam insulation; two inches worth of air gap (or other amounts); and one or more pieces of radiant barrier foil in the center of the air gap for most of the structure (other numbers of radiant barrier layers are also possible). Insulation can be used for structural integrity to be able to mount the radiant barrier. In some embodiments, a panel is actually two subpanels mirror imaged with foil in between.

A cross section of an installed building envelope system can include a canvas cover, an outside insulation panel, an air gap with supporting structure, a radiant barrier, an air gap with supporting structure and an inside insulation panel.

A wrap (e.g., a canvas wrap) can be placed over the entire structure. The canvas can provide weather resistance, structural integrity and an ability to select a color. The color can contribute to the net thermal resistance. A black canvas cover can absorb heat during the winter; a white canvas cover can reflect heat in summer. Different colors, or, e.g., camouflage patterns can also be used for concealment in addition to energy conservation.

In some embodiments, foam insulation can be used for insulation panels due to a good combination of being light and durable. In some embodiments, the insulation is a type that is actually used in conjunction with typical permanent buildings. A durable insulation allows for the panels to resist the set up and striking cycles for temporary buildings. Other foam-based insulation can also be used, such as other polymer-based insulation. Mineral-based insulation (mineral wool, glass fiber, aerogel, etc.) can also be used within the blocks if desirable, e.g., for reasons of cost or additional fire resistance.

Foam insulation can be used to provide structure to support the first air gap. In one embodiment, foam insulation is placed around the edges of a panel to form a tongue and groove connector, and to facilitate assembly of the panels, while simultaneously surrounding and providing the structure, the air gap and the mounting surface for the radiant barrier. In addition, a center strip can also provide structural support for the radiant barrier.

A radiant barrier, consisting of a thin layer of reflective material, can rest on the strips of foam insulation supporting the air gap. In some embodiments a structurally reinforced metal foil (e.g., aluminum) is used. In other embodiments, a radiant barrier is formed with a sheet of metallized polymer. (e.g., aluminized Mylar) A mirror image of the air gap and foam panel can then be placed on the other side.

In some embodiments, more than two air gaps and/or more than one radiant barrier are used. For example, two sets of internal supports and two pieces of metal foil can be used. In some embodiments three or more radiant barriers are used.

Phase change insulation can also be used, as an additional layer that rests on the interior insulation layer, facing the air gap and the radiant barrier, to provide heat transfer resistance via the thermal capacitance effect for which phase change insulation is designed. For example, from the point of view of a roof panel, a phase change insulation sheet based on a wax that melts at about 85° F. can be embedded inside the roof panel. This additional layer of material can further slow heat transfer, because the wax will have to melt completely or significantly before the heat can go past the phase change insulation. For instance, in a desert climate with hot days and cool nights, on a hot summer day of 100° F. outside, excess heat that has worked its way through the top layer of insulation, air gap, radiant barrier and second air gap would then reach the phase change material and stall until sufficient heat has been captured to melt the wax. Until that time at which the wax is melted, the maximum temperature that the air conditioner inside the building would “see” would be 85° F., because the heat energy melts the wax before it is transferred through the next layer of insulation and into the shelter. The temperature at the phase change layer stays at the melting temperature of the wax until the wax has sufficiently melted. By absorbing the heat to make a phase change of the wax, time at a lower temperature is gained.

In some embodiments and by the time the heat has melted the wax, it is possible that sufficient time will have passed that the outside temperature during evening hours is now below 85° F. The wax will start to solidify again because the temperature has dropped below 85° F., the melting point of the wax. As the wax solidifies it releases heat, some of which will escape back up through the top part of the panel, but some of which will escape into the shelter through the bottom part, actually helping to heat the shelter at night. The energy captured by the wax during the day and prevented from getting into the shelter can thus be used by the building to help heat it at night (or vice versa during the opposite season). Depending on the embodiment, a layer of phase change insulation can be placed on the bottom side or the top side of a layer of foam before the air gap.

In some embodiments, assembled panels can be held together by a tongue and groove construction of the panels themselves. The entire structure, once it gets assembled around the shelter, can be held together by lag bolts and/or the covering (e.g., canvas cover). The lag bolts can add additional structural integrity. Although tongue and groove construction is mentioned as a method of inter-panel coupling, other inter-panel couplings are possible. For example, dovetail joints or butt joints are also possible.

In one embodiment, a retrofittable outdoor building envelope system includes several elements. The panels (including insulation, air gaps, radiant barrier and phase change insulation), canvas cover, and tube insulation can all contribute to reducing heat transfer and, correspondingly, reducing energy requirements for heating and/or cooling.

Additional heat transfer prevention or reduction can occur at the door. As the building is small, when the door is opened much of the conditioned air is lost to the environment. Two systems can be used to slow the loss. These include installing a strip curtain at the door and assembling a portable vestibule around the outside of the door. When a person is going in or out, it allows enough time for the door to close before arriving at a second door. This allows trapping of the conditioned air inside the shelter. However, to the extent that the air escapes the shelter, the air escapes to the weatherized enclosure rather than directly to the atmosphere. The vestibule covering can be insulated and/or have a radiant barrier inside.

FIG. 1 is a perspective view 100 illustrating two interlocked panels 102 and 104 of a building envelope system. The panels 102 and 104 can include a tongue 116 and groove 114 coupling 112 allowing the panels 102 and 104 to mate.

The radiant barrier layer 108 and air gap layers 107 and 109 can also be repeated. For example, an alternative panel can include a top insulation layer, top air gap layer, top radiant barrier layer, mid air gap layer, bottom radiant barrier layer, bottom air gap layer and bottom insulation layer. Phase change material can be added inside the panels, usually at the top of the bottom insulation layer or the bottom of the top insulation layer, in either case facing the air gap and first radiant barrier layer.

FIG. 2 is an exploded view illustrating two interlocked panels of a building envelope system consistent with embodiments disclosed herein. A top insulation layer 201 can connect to a top air gap layer 202. The top air gap layer 202 can include a supporting structure 212 and 214 made from strips of insulation or other materials and attached to the top insulation layer 201. A radiant barrier layer 204 can include a radiant barrier 216 that is attached to the supporting structure 212 of the top air gap layer 202. The radiant barrier layer 204 in conjunction with the top air gap layer 202 and top insulation layer 201 form an enclosed air gap that traps air. The radiant barrier 216 of the radiant barrier layer 204 can also be attached to a bottom air gap layer 206. The bottom air gap layer 206 can include a supporting structure 218 and 220 made from strips of insulation or other materials and attached to a bottom insulation layer 208. The insulation 210 and 222 of the insulation layers 201 and 208 can be foam insulation. It should be recognized that other configurations are possible, such as repetition of layers.

FIGS. 3A and 3B show an example of connecting two interlocking panels 304 and 306. FIG. 3A is a perspective view 300 of the two separated interlocking panels 304 and 306. FIG. 3B is a perspective view 302 of the two mated interlocking panels 304 and 306. The interlocking panels 304 and 306 can mate with a tongue and grove connector 312 (which includes a tongue 308 and groove 310) that is formed by the supporting structure of the top and bottom air gap layers and/or the radiant barrier layer 316 (shown in FIG. 2).

FIGS. 5 to 7 show construction of a building envelope system on a portable shelter. FIG. 5 shows a bare shelter 500. FIG. 6 shows a shelter 600 with installed panels 608. FIG. 7 shows a covered shelter 700.

FIG. 5 is a perspective view of the bare shelter 500 consistent with embodiments disclosed herein. Note that the metal outside layer (including walls 502) is exposed to the elements. The bare shelter 500 can be raised up from the ground level on supports to form a level foundation. The bare shelter 500 can include a door 504, climate control system 506 and windows (not shown).

FIG. 6 is a perspective view of the shelter 600 with installed panels 608 of a building envelope system consistent with embodiments disclosed herein. The panels 608 increase outside dimensions of the shelter 600, but leave the inside dimensions of the shelter 600 unchanged. In the embodiment shown, the tongue and groove coupling of the panels 608 allows for a tight fit around the shelter 600. The panels 608 enable the shelter 600 to use less energy, by slowing heat transfer from the shelter 600 to the environment (or from the environment to the shelter 600). The building envelope system can include removable panels that cover a door 604, climate control system 606 and/or windows (not shown).

FIG. 7 is a perspective view of the shelter 700 with installed panels 708 and a covering 710 of a building envelope system consistent with embodiments disclosed herein. In addition to the covering 710, insulation tubes (not shown) can be placed underneath the skirt of the covering 710. Weights, such as sandbags 712, can be placed on the skirt of the covering 710 to help prevent air flow under the shelter 700 and help the covering 710 remain on the shelter 700. In the embodiment shown, the covering leaves the door 704 and climate control system 706 exposed. In some embodiments, the cover can be configured to removably cover the door 704 and climate control system 706.

FIG. 8 is a perspective x-ray view of a shelter 800 storing the building envelope system (panels 808 and covering in a box 810) within the shelter 800 consistent with embodiments disclosed herein. The shelter 800 can be transported with the panels 808, covering (in the box 810), compressible insulation (not shown), vestibule (in a box 812) and/or strip curtains (not shown) within the shelter 800. These items can be stored within the walls 802 of the shelter during transport.

FIG. 9 is a perspective view 900 of a shelter wall 902 including a shelter door 904 with installed strip curtains 914 consistent with embodiments disclosed herein. Strip curtains 914 slow the loss of heat to the environment in heating season when the door 904 is open by slowing and/or blocking airflow and thus blocking or reducing heat loss through mass transfer (or, similarly, working against heat gain in cooling season).

FIG. 10 is a perspective x-ray view of lag bolts 1004 installed in a building envelope system 1000 consistent with embodiments disclosed herein. The lag bolts 1004 can be used in conjunction with panels 1002 to provide additional structural support for the panels 1002. In the example shown, the lag bolts 1004 are used to draw corner panels close together and provide support for the corner panel structure. The lag bolts 1004 can be screwed through a first panel and into insulation layers 1010 and 1022 of a second layer. The lag bolts 1004 made of a non-thermally-conductive material are preferred but thermally conductive lag bolts make up a small portion of the entire structure and, in some embodiments, do not substantially degrade its performance.

FIGS. 11 and 12 show compressible insulation tubes 1116 and 1216 before installation and after installation. FIG. 11 is a perspective view 1100 of the compressible insulation tubes 1116 consistent with embodiments disclosed herein. The compressible insulation tubes 1116 can be used to adjust to varying terrain height underneath a shelter. By using the compressible insulation tubes 1116, a dead air space is constructed under a shelter, which provides additional insulation to the shelter. The compressible insulation tubes 1116 also prevent or reduce active heat transfer through water or air circulation under the shelter. FIG. 12 is a perspective view of a shelter 1200 with the installed compressible insulation tubes 1216 consistent with embodiments disclosed herein. Air and/or water flow is reduced and/or prevented by compressing the compressible insulation tubes 1216 under the shelter. In the embodiment shown, the compressible insulation tubes 1216 are placed under a shelter wall 1202 which includes a door 1204.

FIGS. 13 and 14 show a vestibule addition to the shelter. FIG. 13 is a front view of a shelter 1302 with an installed vestibule frame 1318. The vestibule frame 1318 can be constructed in front of the shelter door. Depending on the embodiment, the vestibule frame 1318 can or is not attached to the shelter 1302 and/or building envelope system. If not attached, the vestibule can rest against the building envelope system. A material, such as canvas, can be overlaid on the vestibule frame 1318 to form the vestibule.

FIG. 14 is a front view 1400 of a shelter 1402 with a vestibule 1420. The vestibule 1420 can be used to capture air from the shelter 1402 and help prevent or reduce total air exchange of the shelter 1402 with environmental air. The vestibule 1420 can be seen as a buffer between the environment and the conditioned air. The buffer of the vestibule 1420 can be enhanced by further insulating the vestibule 1420, such as by providing insulation and/or radiant barrier construction within the construction of a vestibule covering 1422.
